Description

The Hydrocarbon Ethylene (C2H4) is a Gaseous Plant hormone, which is involved in a multitude of Physiological and Developmental processes. Responses to Ethylene include Fruit Ripening, Leaf Senescence and Abscission, Promotion or Inhibition of Seed Germination, Flowering and Cell Elongation. Environmental Stresses, such as Chilling, Flooding, Wounding and Pathogen Attack increase Ethylene Synthesis and thereby control Gene Expression. A combination of genetic, biochemical, and molecular approaches is uncovering this remarkable signaling pathway in plants. Although the initial hunt for the major elements of the Ethylene pathway was performed in the model plant Arabidopsis thaliana, identification and functional analysis of the corresponding genes in other plant species uncovered a high degree of conservation of this Signaling Cascade in the Plant Kingdom.
